Table 3.

A comparison of the neuronal populations responding to various types of natural stimuli at the two post-operative periods

	Post-operative day 7–10		Post-operative day 14–17
	Spinal nerve ligation	Sham-operated	Spinal nerve ligation	Sham-operated
Brush	95%*	78%	60%	60%
Prod	100%	95%	78%*	100%
Acetone	66%	40%	26%	26%
Mechanical punctate	98%	87%	85%	91%
Thermal	95%	87%	91%	97%

A higher proportion of neurones of SNL rats at PO days 7–10 responded to brush stimuli compared with the responsive neuronal population of sham-operated rats at this time point

^*P = 0.02. A smaller proportion of neurones of SNL rats at PO days 14–17 responded to prod stimuli compared with the responsive neuronal population of sham-operated rats at this time point

^*P = 0.007.
